SN74ALS137ANG4 Application Field and Working Principle

The SN74ALS137ANG4 is part of the 140 series of general purpose logic devices from Texas Instruments, which includes many multiplexers, encoders, decoders and signal switches. This device is just one of the vast range of multiplexers from TI, which are all produced to the same industrial standard and based on the same set of fundamental principles.

What is SN74ALS137ANG4?

The SN74ALS137ANG4 is a 16-channel multiplexer, which can be used to switch an analog or digital signal between sixteen different outputs. It can be used for data acquisition, signal switching and switching between digital or analog signals, as well as a range of other applications. This device is designed to withstand an input voltage of up to 5V and has a maximum of 6 outputs in a single configuration.

Features of SN74ALS137ANG4

The SN74ALS137ANG4 includes some key features, such as a low-power CMOS technology, which supports low-voltage operations, high-speed operation and signal switching. It includes sixteen pins, with two Ground (GND) pins, two Select (S1 and S2) pins, one Enable (EN) pin, four Data Input (D0..D3) pins, two Output (O1..O2) pins and five Reset (R1..R5) pins. It also features a 2-input logic SCHRFT(SCHRFT-L), a 4-input logic SCHRFT(SCHRFT-M) and a 7-input logic SCHRFT(SCHRFT-H). In addition, the device includes two voltage reference pins, a continuous current rating of 4.7V and a maximum operating temperature of +70℃.

Working Principle of the SN74ALS137ANG4

The SN74ALS137ANG4 works on the principle of multiplexing. It is an integrated circuit (IC) that has sixteen input pins and an output pin. These pins are used to switch an analog or digital signal from one of the sixteen inputs to one of the four outputs. The device works by using two select pins (S1 and S2) to select one of the sixteen input channels, and one enable pin (EN) to enable the output. The S1 and S2 select pins determine which of the four outputs to switch the signal to, and the D0 to D3 input pins select which of the sixteen input channels is used.

When the EN pin is set to High, the output of the SN74ALS137ANG4 is enabled, and when it is set to Low, the output of the SN74ALS137ANG4 is disabled. The two Reset (R1..R5) pins allow the device to be reset, and the two voltage reference pins allow the output voltage to be adjusted.

Applications

The SN74ALS137ANG4 is suitable for a wide range of applications, including data acquisition, signal switching, and switching between digital or analog signals. It can be used in applications such as video and audio production as well as a variety of industrial and consumer electronics.

The device is also used in a variety of automotive applications, such as automotive navigation systems, air conditioning systems, and engine control units. In addition, the device is used in robotic systems, which integrate sensors, motors and actuators. This device is also used in other fields, such as telecommunication, medical, and test and measurement applications.

Conclusion

The SN74ALS137ANG4 is a versatile multiplexer with sixteen channels, low-power CMOS technology, two select pins and an enable pin. It can be used for a range of applications, including data acquisition and signal switching, as well as a variety of automotive and robotic systems.
